WebMay 1, 2003 · The key mission of Chk1 and Chk2 is to relay the checkpoint signals from the proximal checkpoint kinases of the phosphatidylinositol 3-kinase family, particularly ATM and ATR, and likely also the newly identified ATX ( Abraham, 2001, Shiloh, 2003, Kastan and Lim, 2000; and R. Abraham, personal communication), which phosphorylate and activate … WebCHK1 is an evolutionarily conserved protein kinase that functions to ensure genomic integrity upon genotoxic stress.
